JOHN L. MORAN AND ALVIN J. rnn orjsro'xmn, vwhen:Heron, .AssrGNoRs, BY DIRECT AND, IMESNE ASSIGNMENTS, vOF ONE-FOURTH TO FRANCIS E. P. WILDER, OF SPOKANE; WASHING-TGIF, vAND QNE-FOURTHVTO ROBERT MALCOM; OF "CHICAGO,

ILLINOIS Applicatibn filed May 28:,

Our present invention relates'tdimprove ments in goggles which, while adapted for various uses, are especially designed for use by mechanics, machinists, and Others, While at work with welding torches, abrading wheels, &c., to protect the eyes, "and eyeglasses or spectacles when the latterinstruments are worn by the Workman. l

As is .well known, the magnifying lenses of the eye-glassesor spectacles are very ex pensive ascompared with the plane glass paratively cheap. goggle-lenses, and "these goggles, but also to protect the spectacles latter may with facility and without excessive cost be replaced.

Our invention therefore is designed not only to protect the eyes of the Wearer'of the habitually worn by the Workman, and to this end the invention consists in certain novel combinations and arrangements of parts whereby I the goggles may be 'Worn; with comfort, and whereby the I goggles}- are equipped to perform their required functions with reliability and effectiveness. r Y H In the accompanying drawings We have il lustrated one complete example of the physical embodiment of our invention wherein the parts are combined and arranged accord;

ing to the best mode We have'thus far de vised for the practical application ofthe principles of our invention. i

may be formed from plastic material in suitable presses and then hardened for use. J Theflens 1 ineach cupis retained back of the front retaining flange 2. of the cup by means of a removable retaining ring 3, which has externa'l screw threads engaging complementaryscrewthreads arranged in the cup and spaced back of the front flange as shown 1n F gure 4, i The retaining ringjis provided withnotchesas 4 to" receive the finger andthumb nails and facilitate turning of the re-,!

taining ring as it is screwed into place'to clamp the lens, or forwithdraWingthe ring for the purpose of replacing a marred lens.

The two cups are joined by a. flexible v bridge-strap 5 thatispassed through slots 6 a vertically disposed in complementary flanges 7 which project from the cups and extend toward the vertical,center line of the goggles, and'Qbythe use ofthis flexible connection the cups readily'adjust themselves for use. As

seen in Figure 1 these flanges are located above the horizontal axis of the goggles, and theflexible bridge strap is thus disposed di- '-rectly front of the bridge piece of thespectacles worn by the wearer of the goggles, and

back of the goggles. I

of the flanges and the corre- V Thewidthsp'onding, wide strap,insure a stable bridge joint between the cups of the goggles, and assist in maintainingthe cups 'in position over the spectacle lensesin' such; manner as to provide for the comfort of the wearer of the spectacles and the enclosing goggles. "In order to provide a neat; and effective fit "between the cups of the goggles "and the o o cheeksadjacent the nose-bridge of the gogsectional new of a =gles,lwe employ a' flexible cushion-strip 8,

arcuate groovef9 finthe rear face'fof each cup il hiselastic, flexiblejcu'shion strip or shield.

"preferablyof sheetrubber, or other suitable materia-Lwhichhas its edge embedded inan may readily be compressed, or its shape otherwise changed in adaptin it to its purpose of closing the inner sideo the cup against ingress of particles of metal, dust &c., as for instance when the goggles are being worn by a workman at an abrading wheel.

It will be noted that the walls of the cups are cut away at their inner, adjoining edges or sides, and this rubber cushion or flexible wall insures a complete closure of any aperture that would otherwise occur at the inner side of a cup.

At the outer sides of the respective cups, where the walls reach their maximum length, the cups are fashioned with out-set templehousings 10. The rear edges of the cups have a curvature to conform to the facial contoursurrounding the eyes, and the outer wall of each temple housing terminates at the rear in an outwardly flared flange 11 having a slot 12 for the attachment of the ends of an elastic band or strap 13 which passes around the ings and bridge flanges provides for a spaced relation of the lenses of the spectacles and the lenses of the goggles, thereby preventing frictional contact between the sets of lenses, and insuring comfort to the wearer of the gog les and spectacles.

e temple housings fit neatly over the bin e joints at the rear ends of the temples or earars of the spectacles and the flanges 7 and cushion-strips 8 of the cups provide -for a comfortable support of the goggles over the bridge of the spectacles.

Each cup is fashioned with a ventilating opening or aperture as 15 and 16 respectively to provide a circulation of air within the cups and thus prevent accumulation of moisture on the lenses, as well as insuring proper conditions within the cups for the eyes. The vent openings are provided with filtering screens made up of an inner mesh 17 and an outer mesh 18, with a filter 19 between the meshes. This filter material may be steel wool or other suitable material that will prevent ingress of fine particles of dust, and yet permit the required circulation of air through the vent openings for the purpose desired.

Having thus fully described our invention, what we claim as new and desire to secure by Letters Patent is 1. The combination in a pair of goggles with complementary cups, of integral slotted bridge-flanges on the cups and a bridgestrap, saidv flanges being spaced back of the 66 lens of each cup, an integral, outset temple housing on each cup having its front wall terminating back of the lens of the cup, up-

r and lower vent openings in the cups, and rubber shields seated in grooves adjacent the bridge flanges forming continuations of the rear edges of the cups. 7

2. In goggles of the character described provided with a pair of eye-cups flexibly connected together, each eye-cup on the nose side thereof at a point above the transverse axis of the cu and rearward of the lensseat of the cup ing provided with a slotted flange disposed toward the other eye-cup; the side walls of each cup terminating ad acent to the marginal edges of said flange, the rear face of each cup being provided with a roove in alignment with the side wall; a exible cushion strip edgewisely inserted in said groove to constitute a flexible closure for the inner side of each cup; while the outer temple side of each cup is formed with an integral out-set portion extending from a point rearward of the lens-seat to the face-engaging perimeter and terminating in a laterally disposed sloitedhead band attaching flange.

3. In goggles of the character described having a pair of eye-cups flexibly connected together, each eye-cup on its nose side rearward of and above the transverse axis having a laterally extendingslotted flange disposed toward the other eye-cup; the side walls of each cup terminating adjacent to said flange; a strip of flexible material secured to the cup so as to constitute a closure for the side wall openin across said flange; the outertemple side 0 each eye-cup rearward of the lens holding end being out-set to provide a spectacle arm receiving socket disposed transversely of the side wall and terminating in an outwardly disposed slotted head band attaching flange; vent openings in the top and bottom side walls of each cup provided with spaced apart screens; and filtering material arranged between said screens.

4. In goggles of the character described having a pair of eye-cups flexibly connected together, each eye-cup in its top and bottom side walls bein provided with openings; screens arranged in spaced relation across said openings and secured to the side walls; and a porous filtering medium arranged between the spaced screens throughout said openings.

In testimony whereof we aflix our signatures.
